Download the latest version of fw from here on abi or sandisk, un-zip fw, drag and drop to the root of the player. Disconnect from pc and allow it time to update itself. If you are not comfortable with doing this yourself, sandisk has a tool called the "firmware updater" which you can download from sandisk and it does it for you. But learning the manual method is best, as you can upgrade downgrade and eventually even rockbox your player
